  • Patent number: 11436971
    Abstract: A display driving apparatus includes an output control circuit configured to, with one frame being divided into a plurality of blank periods by touch driving, output source signals corresponding to display data during the plurality of blank periods; and a polarity control circuit configured to receive pre-polarity control information for polarity inversion, and control polarities of the source signals outputted from the output control circuit, for polarity inversion by the unit of vertical 2 dots for one frame, wherein polarities for pre dummy lines and active data lines of odd-numbered and even-numbered blank periods are controlled by the pre-polarity control information.
    Type: Grant

  • Patent number: 10885824
    Abstract: Embodiments of the present disclosure relate to a display driving device and a display device including the same. The display driving device includes a source driving circuit configured to convert image data of respective channels into source signals; a polarity control circuit configured to receive polarity data for the respective channels, and generate a polarity control signal for controlling polarities of the source signals depending on a logic combination of the polarity data; and a multiplexer circuit configured to output the source signals to data lines in response to the polarity control signal.
